Dyno at Altitude

Hi everyone, I’m new here but thought I would post the baseline dyno results before I add mods here in Denver. The first is corrected and the 2nd uncorrected.

Good data. This is an excellent example of how correction factors for FI cars at altitude is extremely inflated.

what does corrected and uncorrected mean?

Uncorrected means the actual HP/TQ the dyno recorded (aka the real number). The Correction Factor is a multiplier that will increase/decrease the actual value based on atmospheric conditions -- barometric pressure, temp and humidity -- in attempt to standardize the number. In this case the SAE correction is at 1.21 meaning it's adding 21% to the Uncorrected number to simulate what the output might be based on some industry standard formulas. My point being that with the 1.21 CF resulting in ~370WHP is inflated since these cars have all been extremely consistent in the 335WHP range closer to sea level where the corrections are less extreme. Low 300's at altitude shows some of the beauty of FI and modern computers that will try to always target a specific TQ value (within some bounds), regardless of conditions.
